  • jquery append row onclick

    - by BigDogsBarking
    Pretty new to jQuery, so I'm hoping someone can help me out... There's a couple of things going on here... Help with any part of it is appreciated. For starters, I'm trying to append a row to a table when a user clicks in the first enabled input field for that row. Here's the code I'm trying to use: $("#fitable > tbody > tr > td > input").bind('focus', function() { if($(this).attr('disabled', false)) { $(this).click(function() { var newRow = '<tr><td><input name="f1[]" value="" /><label>CustNew</label></td><td><input name="field_n1[]" value="" /><label>N1</label></td><td><input name="field_n2[]" value="" /><label>N2</label></td></tr>'; $(this).closest("tbody").append(newRow); }); } }); If it's helpful, here's the html: <table id="fitable"> <tbody> <tr valign="top"> <td><input disabled="disabled" name="cust" id="edit-cust" value="[email protected]" type="text"><label>Cust</label></td> <td><input name="field_n1[]" value="" type="text"><label>N1</label></td> <td><input name="field_n2[]" value="" type="text"><label>N2</label></td> </tr> </tbody> </table>

  • C++ missing feature: variables with mutating names

    - by user345671
    Hello. Can someone please add a feature to C++? I would like to change variable names depending on the context. Example: Class stuff; if(stuff.hasSuperPowers()) { stuff becomes stuffWithSuperPowers; } That because creating a new variable and using an assignment sucks and lets stuff be acessible in that scope anyway. If you do it, please keep the becomes syntax unless it doesn't look good enough for you as a native English speaker. Thanks in advance.

  • CREATE VIEW called multiple times not creating all views

    - by theninepoundhammer
    Noticing strange behavior in SQL 2005, both Express and Enterprise Edition: In my code I need to loop through a series of values (about five in a row), and for each value, I need to insert the value into a table and dynamically create a new view using that value as part of the where clause and the name of the view. The code runs pretty quickly, but what I'm noticing is that all the values are inserted into the table correctly but only the LAST view is being created. Every time. For example, if the values I'm using are X1, X2, X3, X4, and X5, I'll run the process, open up Mgmt Studio, and see five rows in the table with the correct five values, but only one view named MyView_x5 that has the correct WHERE clause. At first, I had this loop in an SSIS package as part of a larger data flow. When I started noticing this behavior, I created a stored proc that would create the CREATE VIEW statement dynamically after the insert and called EXECUTE to create the view. Same result. Finally, I created some C# code using the Enterprise Library DAAB, and did the insert and CREATE VIEW statements from my DLL. Same result every time. Most recently, I turned on Profiler while running against the Enterprise Edition and was able to verify that the Batch Started and Batch Completed events were being fired off for each instance of the view. However, like I said, only the last view is actually being created. Does anyone have any idea why this might be happening? Or any suggestions about what else to check or profile? I've profiled for error messages, exceptions, etc. but don't see any in my trace file. My express edition is 9.00.1399.06. Not sure about the Enterprise edition but think it is SP2.

  • How to fix this simple SQL query?

    - by morpheous
    I have a database with three tables: user_table country_table city_table I want to write ANSI SQL which will allow me to fetch all the user data (i.e. user details including the name of the country of the last school and the name of the city they live in now). The problem I am having is that I have to use a self join, and I am getting slightly confused. The schema is shown below: CREATE TABLE user_table (id int, first_name varchar(16), last_school_country_id int, city_id int); CREATE TABLE country_table (id int, name varchar(32)); CREATE TABLE city_table (id int, country_id int, name varchar(32)); This is the query I have come up with so far, but the results are wrong, and sometimes, the db engine (mySQL), asks me if I want to show all [HUGE NUMBER HERE] results - which makes me suspect that I am unintentionally creating a cartesian product somewhere. Can someone explain what is wrong with this SQL statement, and what I need to do to fix it? SELECT usr.id AS id, usr.first_name, ctry1.name as loc_country_name, ctry2.name as school_country_name, city.name as loc_city_name FROM user_table usr, country_table ctry1, country_table ctry2, city_table city WHERE usr.last_school_country_id=ctry2.id AND usr.city_id=city.id AND city.country_id=ctry1.id AND ctry1.id=ctry2.id;

  • How to determine the inner context node within an XSLT select

    - by Marcus Rickert
    Hi there! I'm trying to determine a subset of nodes stored in the variable objs by using a user defined function cube:is_active: <xsl:variable name="active_cubes" select="$objs[cube:is_active(XXX) = 'TRUE']"/ Since the function does not allow a local context I'm required to pass it as a parameter (denoted by XXX). However, the usual suspects "." or "current()" do not work since they refer to context node of the surrounding block and NOT to the current element of objs which is evaluated. The only solution so far which DOES work is: XXX=SOME_CHILD_TAG/.. But this is really ugly since it depends on the existence of the child tag for the parent node to work correctly. Is there any other way? Thanks!

  • Greasemonkey failing to GM_setValue()

    - by HonoredMule
    I have a Greasemonkey script that uses a Javascript object to maintain some stored objects. It covers quite a large volume of information, but substantially less than it successfully stored and retrieved prior to encountering my problem. One value refuses to save, and I can not for the life of me determine why. The following problem code: Works for other larger objects being maintained. Is presently handling a smaller total amount of data than previously worked. Is not colliding with any function or other object definitions. Can (optionally) successfully save the problem storage key as "{}" during code startup. this.save = function(table) { var tables = this.tables; if(table) tables = [table]; for(i in tables) { logger.log(this[tables[i]]); logger.log(JSON.stringify(this[tables[i]])); GM_setValue(tables[i] + "_" + this.user, JSON.stringify(this[tables[i]])); logger.log(tables[i] + "_" + this.user + " updated"); logger.log(GM_getValue(tables[i] + "_" + this.user)); } } The problem is consistently reproducible and the logging statments produce the following output in Firebug: Object { 54,10 = Object } // Expansion shows complete contents as expected, but there is one oddity--Firebug highlights the array keys in purple instead of the usual black for anonymous objects. {"54,10":{"x":54,"y":10,"name":"Lucky Pheasant"}} // The correctly parsed string. bookmarks_HonoredMule saved undefined I have tried altering the format of the object keys, to no effect. Further narrowing down the issue is that this particular value is successfully saved as an empty object ("{}") during code initialization, but skipping that also does not help. Reloading the page confirms that saving of the nonempty object truly failed. Any idea what could cause this behavior? I've thoroughly explored the possibility of hitting size constraints, but it doesn't appear that can be the problem--as previously mentioned, I've already reduced storage usage. Other larger objects save still, and the total number of objects, which was not high already, has further been reduced by an amount greater than the quantity of data I'm attempting to store here.

  • SQL trigger to delete rows from database

    - by wpearse
    I have an industrial system that logs alarms to a remotely hosted MySQL database. The industrial system inserts a new row whenever a property of the alarm changes (such as the time the alarm was activated, acknowledged or switched off) into a table named 'alarms'. I don't want multiple records for each alarm, so I have set up two database triggers. The first trigger mirrors each new record to a second table, creating/updating rows as required: CREATE TRIGGER `mirror_alarms` BEFORE INSERT ON `alarms` FOR EACH ROW INSERT INTO `alarm_display` (Tag,...,OffTime) VALUES (new.Tag,...,new.OffTime) ON DUPLICATE KEY UPDATE OnDate=new.OnDate,...,OffTime=new.OffTime The second trigger should execute after the first and (ideally) delete all rows from the alarms table. (I used the Tag property of the alarm because the Tag property never changes, although I suspect I could just use a 'DELETE FROM alarms WHERE 1' statement to the same effect). CREATE TRIGGER `remove_alarms` AFTER INSERT ON `alarms` FOR EACH ROW DELETE FROM alarms WHERE Tag=new.Tag My problem is that the second trigger doesn't appear to run, or if it does, the second trigger doesn't delete any rows from the database. So here's the question: why does my second trigger not do what I expect it to do?

  • What is the best way to do scoped finds based on access control rules in Rails?

    - by Rafael Szuminski
    Hi I need to find an elegant solution to scoped finds based on access control rules. Essentially I have the following setup: Users Customers AccessControl - Defines which user has access to another users data Users need to be able to access not just their own customers but also shared customers of other users. Obviously something like a simple association will not work: has_many :customers and neither will this: has_many :customers, :conditions => 'user_id in (1,2,3,4,5)' because the association uses with_scope and the added condition is an AND condition not an OR condition. I also tried overriding the find and method_missing methods with the association extension like this: has_many :customers do def find(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end def method_missing(*args) #get the user_id and retrieve access conditions based on the id #do a find based on the access conditions and passed args end end but the issue is that I don't have access to the user object / parent object inside the extension methods and it just does not work as planned. I also tried default_scope but as posted here before you can't pass a block to a default scope. Anyhow, I know that data segmentation and data access controls have been done before using rails and am wondering if somebody found an elegant way to do it. UPDATE: The AccessControl table has the following layout user_id shared_user_id The customer table has this structure: id account_id user_id first_name last_name Assuming the the following data would be in the AccessControl table: 1 1 1 3 1 4 2 2 2 13 and so on... And the account_id for user 1 is 13 I need to be able to retrieve customers that can be best described with the following sql statement: select * from customers where (account_id = 13 and user_id = null) or (user_id in (1,3,4))

  • How to use Eclipse's Display View for Debug?

    - by jzd
    At the link below it explains that the "display view allows you to manipulate live code in a scrapbook type fashion (see Figure 8). To manipulate a variable, simply type the name of the variable in the Display view, and you'll be greeted with a familiar content assist." http://www.ibm.com/developerworks/library/os-ecbug/ However, I am having trouble getting it to work. I have the view open but all the buttons are disabled. I have tried putting code in the view, selecting code in the view, selecting code in other views, while running and while not running debug, but the only button that is ever enabled on the view is "clear console". Suggestions on what I am doing wrong?

  • Can fields of the class and arguments of the method interfere?

    - by Roman
    I have a class with a fields called "a". In the class I have a method and in the list of arguments of this method I also have "a". So, which "a" I will see inside of the method? Will it be the field or it will be the argument of the method? public class myClass { private String a; // Method which sets the value of the field "a". public void setA(String a) { a = a; } } By the way, there is a similar situation. A method has some local (for method) variables whose names coincide with the names of the fields. What will the "see" the method if I refer to such a method-local variable inside the method (the field or the local variable)?

  • Why is Routes.rb not loading the IPs from cache?

    - by Christian Fazzini
    I am testing this in local. My ip is 127.0.0.1. The ip_permissions table, is empty. When I browse the site, everything works as expected. Now, I want to simulate browsing the site with a banned IP. So I add the IP into the ip_permissions table via: IpPermission.create!(:ip => '127.0.0.1', :note => 'foobar', :category => 'blacklist') In Rails console, I clear the cache via; Rails.cache.clear. I browse the site. I don't get sent to pages#blacklist. If I restart the server. And browse the site, then I get sent to pages#blacklist. Why do I need to restart the server every time the ip_permissions table is updated? Shouldn't it fetch it based on cache? Routes look like: class BlacklistConstraint def initialize @blacklist = IpPermission.blacklist end def matches?(request) @blacklist.map { |b| b.ip }.include? request.remote_ip end end Foobar::Application.routes.draw do match '/(*path)' => 'pages#blacklist', :constraints => BlacklistConstraint.new .... end My model looks like: class IpPermission < ActiveRecord::Base validates_presence_of :ip, :note, :category validates_uniqueness_of :ip, :scope => [:category] validates :category, :inclusion => { :in => ['whitelist', 'blacklist'] } def self.whitelist Rails.cache.fetch('whitelist', :expires_in => 1.month) { self.where(:category => 'whitelist').all } end def self.blacklist Rails.cache.fetch('blacklist', :expires_in => 1.month) { self.where(:category => 'blacklist').all } end end

  • Explicitly typing variables causes compiler to think an instance of a builtin type doesn't have a pr

    - by wallacoloo
    I narrowed the causes of an AS3 compiler error 1119 down to code that looks similar to this: var test_inst:Number = 2.953; trace(test_inst); trace(test_inst.constructor); I get the error "1119: Access of possibly undefined property constructor through a reference with static type Number." Now if I omit the variable's type, I don't get that error: var test_inst = 2.953; trace(test_inst); trace(test_inst.constructor); it produces the expected output: 2.953 [class Number] So what's the deal? I like explicitly typing variables, so is there any way to solve this error other than not providing the variable's type?

  • Hibernate NamingStrategy implementation that maintains state between calls

    - by Robert Petermeier
    Hi, I'm working on a project where we use Hibernate and JBoss 5.1. We need our entity classes to be mapped to Oracle tables that follow a certain naming convention. I'd like to avoid having to specify each table and column name in annotations. Therefore, I'm currently considering implementing a custom implementation of org.hibernate.cfg.NamingStrategy. The SQL naming conventions require the name of columns to have a suffix that is equivalent to a prefix of the table name. If there is a table "T100_RESOURCE", the ID column would have to be named "RES_ID_T100". In order to implement this in a NamingStrategy, the implementation would have to maintain state, i.e. the current class name it is creating the mappings for. It would rely on Hibernate to always call classToTableName() before propertyToColumnName() and to determine all column names by calling propertyToColumnName() before the next call to classToTableName() Is it safe to do that or are there situations where Hibernate will mix things up? I am not thinking of problems through multiple threads here (which can be solved by keeping the last class name in a ThreadLocal) but also of Hibernate deliberately calling this out of order in certain circumstances. For example Hibernate asking for mappings of three properties of class A, then one of class B, then again more attributes of class A.

  • oracle select query - index on multiple columns

    - by CC
    Hello. I'm working on a sql query, and trying to optimise it, because it takes too long to execute. I have a few select and UNION between. Every select is on the same table but with different condition in WHERE clause. Basically I have allways something like : select * from A where field1 <"toto" and field2 IN (...) UNION select * from A where field1 >"toto2" and field2 =(...) UNION .... I have a index on field1 (it a date field, and field2 is a number). Now, when I do the select and if I put only WHERE field1 <'12/12/2010' it does not use the index. I'm using Toad to see the explain plain and it said: SELECT STAITEMENT Optimiser Mode = CHOOSE TABLE ACCESS FULL It is a huge table, and the index on this column is there. Any idea about this optimiser ? And why it does not uses the index ? Another question is , if I have where clause on field1 and field2 , I have to create only one index, or one index for each field ? Thanks alot.

  • many to many relationship mysql select

    - by zeina
    Let's consider 2 tables "schools" and "students". Now a student may belong to different schools in his life, and a school have many students. So this is a many to many example. A third table "links" specify the relation between student and school. Now to query this I do the following: Select sc.sid , -- stands for school id st.uid, -- stands for student id sc.sname, -- stands for school name st.uname, -- stands for student name -- select more data about the student joining other tables for that from students s left join links l on l.uid=st.uid -- l.uid stands for the student id on the links table left join schools sc on sc.sid=l.sid -- l.sid is the id of the school in the links table where st.uid=3 -- 3 is an example this query will return duplicate data for the user id if he has more than one school, so to fix this I added group by st.uid, yet I also need the list of school name related to the same user. Is there a way to do it with fixing the query I wrote instead of having 2 queries? So as example I want to have Luci of schools ( X, Y, Z, R, ...) etc

  • typedef resolution rule

    - by kumar_m_kiran
    Hi All, Can you Please tell me the resolution rule involved in resolving the meaning of the variable in a typedef. Any link related to the same will be very useful. Example #typedef string* pstring; const pstring parr; Here confusion arises whether const'ness is for pointer or the content. Now based on what thumb rule do can we start resolving the above interpretation of the pstring?. Smilarly, If I have a very complex typedef'ed variable, like #typedef void (func*)()(int), I should be able to resolve it using the thumb rule. Thanks in advance for your suggestions
